<span>Reduce 7y + 2y^2 - 7 by 3 - 4y.
</span>its mean subtract 3 - 4y from 7y + 2y^2 - 7
so
7y + 2y^2 - 7 - (3 - 4y)
= 2y^2 + 7y -7 - 3 + 4y
= 2y^2 + 11y - 10

hope it helps

Does the absolute value graph below flips or not flips? F(x)=2|x-9|+3
True [87]

Answer:

The absolute value graph below does not flip.

Step-by-step explanation:

New graphs are made when transformed from their parents graphs. The parent graph for an absolute value graph is f(x) = |x|.

The equation used for a new graph transformed from the parent graph is in the form f(x) = a |k(x - d)| + c.

"a" shows vertical stretch (a>1) or vertical compression (0<a<1), and <u>flip across the x-axis if "a" is negative</u>.

"k" shows horizontal stretch (0<k<1) or horizontal compression (k>1), and <u>flip across the y-axis if "k" is negative</u>.

"d" shows horizontal shifts left (positive number) or right (negative number).

"c" shows vertical shifts up (positive) or down (negative).

The function f(x)=2|x-9|+3 has these transformations from the parent graph:

a = 2; Vertical stretch by a factor of 2

k = 1; No change

d = 9; Horizontal shift right 9 units

c = 3; Vertical shift up 3 units

Since neither "a" nor "k" was negative, there were no flips, <u>also known as reflections</u>.

Craig bought a treadmill for $400. He estimates that the annual costs to maintain the machine will be $36. Which rational functi
Lorico [155]

Given that Craig bought a treadmill for 400 dollars.

Useful life of the macine = x

Hence annual purchase cost spread over x years will be 400/x per year.

In addition, there is an annual maintenance cost of 36 dollars.

Hence Average annual cost in dollars = purchase cost per year+maintenance cost per year

= \frac{400}{x} +36 \\= \frac{400+36x}{x}

Hence answer for rational function is

either \frac{400}{x} +36[tex]Or [tex]\frac{400+36x}{x}
